A bacterial colony started with 4,400 live cells. As part of an experiment, the colony is exposed to radiation, which kills the cells at a rate of 90 cells per second. 1. Find an equation that expresses the number of cells left living in the bacterial colony in terms of the number of seconds the colony has been exposed to radiation. y = + 2. What is the y-intercept? Interpret it. y-intercept: (x, y) = If the bacterial colony is exposed to radiation for seconds (that is, if the bacterial colony isn't exposed to radiation), there will be living cells in the colony.

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
